CH3COOCHCH2----->3H2O C3H6O2------->3H2O 86x+74y=3,08 3x+3y=0,12 ------->x=0,01; y=0,03 =>Câu A

(RCOO)3C3H5---------------->3RCOONa 7,9*3/(3*R+173)=8,6/(R+67)=>R=47.66667 =>mol (RCOO)3C3H5=0,025=mol C3H5(OH)3=>CÂU A

3CH3COOH+C3H5(OH)3=>(CH3COO)3C3H5+3H2O neste=0,1 mol o,4/3<0,2/1 => hiệu suất tính theo nCH3COOH nCH3COOH pu=0,1.3=0,3 %H=0,3/0,4=75%=>B
